The device for the reclosing lock structure related to the opening and closing of the lid, the device for preventing the unauthorized opening, and the device for forming the planned opening portion by discontinuous breaks are individually applied to the paper container. There was no paper container in which these techniques were applied in a composite manner.
On the other hand, in recent confectionery products, there is a tendency not to use a transparent cover film which has been conventionally used in order to simplify the packaging form. Since this transparent cover film was very effective in preventing unauthorized opening and mixing of foreign objects, it has a function to prevent unauthorized opening and prevent foreign objects from entering in paper containers that do not use transparent cover film. A combination of these technologies that can be easily opened when a legitimate buyer opens, and prevents the lid from being inadvertently opened during use of the once opened paper container. It has come to be desired to include it.
In view of the above circumstances, the present invention has functions of preventing unauthorized opening and preventing foreign matter contamination in a single paper container, and facilitates initial opening of the lid, and can easily lift the lid inadvertently during use. It is an object of the present invention to make it possible to prevent this problem and to make it possible to appeal the safety of products using this paper container to consumers.

The present invention is made in consideration of the above problems, and includes a box body including a front plate, a back plate, left and right side plates, and a bottom plate and having an upper surface as an outlet, and a folding portion on an upper side portion of the back plate. A paper container provided with a lid that is connected and covers the outlet so as to be openable and closable;
A front hanging plate that is connected to the front plate when the lid is closed is connected to the front side portion of the lid, and a horizontal hanging plate that is connected to the left and right side plates when the lid is closed is connected to the left and right side portions of the lid. ,
Each said horizontal board sticks the 1st area | region divided by the breakable separation line at the rear part of this horizontal board to the said side plate, and isolate | separates at the time of container opening by a lid body raising Having means,
The front drooping plate has second tampering restricting means for attaching a second region connected via a breakable separation line to the front plate and separating the container when the container is opened by raising the lid, and the front drooping plate the inner surface of the plate, have a lid opening prevention means comprising step portions for engaging with the disengageably in engagement tongues brought down folding surface side of the front plate from the upper side portion of the front plate,
The locking tongue pieces are respectively located on both end sides of the upper side portion of the front plate, and the upper side portions of the front plate between the locking tongue pieces are provided in a recessed shape so as to protrude downward. Provided is a paper container characterized in that a portion between the upper portions of both sides of the front plate where the tongue piece is folded is a portion where the front plate is not present, thereby solving the above-mentioned problems. .

  The box body is provided with a partition, and the partition includes a pair of connected upright plates and a locking piece formed by cutting a proximal end of each of the rising plates. The pair of upright plates except the pair of upright plates are folded up in a mountain shape, and the lock piece at the base end of the other upright plate is inserted into the lock piece release hole of one upright plate base end formed by folding up the pair of upright plates. It is good to have a configuration that locks and maintains the folded state of the pair of upright plates.

In the present invention, each of the horizontal hanging plates of the lid body has the first unauthorized opening restriction means attached to the side plate in a state where it can be easily separated, and the front hanging plate of the lid body is also in a state where it can be easily separated. Since there are second tampering restriction means affixed to the front plate, there are three tampering restriction means, and even if the lid is lifted with a slight force for the purpose of tampering, the slight force Then, the resistance is so large that the lid cannot be lifted, and the lid is actively prevented from being tampered with. In addition, it is clear that the unauthorized opening restriction means remain on each of the three sides of the box body when attempting to open it illegally, so that illegal acts such as putting in foreign objects from any of the three sides are ensured. Can be prevented.
And while having a tremendous effect on such unauthorized opening regulation, if it is an authorized purchaser, the lid can be easily lifted and the opening operation is simple, and the lid after opening Even in the case of closing, it is possible to prevent the lid from being carelessly lifted by the locking means of the front hanging plate. In addition, the space between the facing surfaces of the three-sided drooping plate and the three-side faceplate of the box body is small, and foreign matter can be reliably prevented from being mixed.

  In addition, the above-mentioned partition has a simple structure, and even if this partition is arranged in the box body, it does not greatly increase the manufacturing cost, and can be a paper container that partitions and holds the stored items appropriately. .

Next, the present invention will be described in detail based on the embodiment shown in FIGS.
In the figure, reference numeral 1 denotes a paper container. As shown in FIG. 2, which is a form after opening the paper container 1, a box body 3 having an upper surface as an outlet 2 and a lid for covering the outlet 2 of the box body 3 The body 4 and the partition 5 disposed in the box body 3 are provided in the box body 3 in a state in which a plurality of plate-like storage items A are partitioned and arranged by the partition 5. It is what is stored.
As shown in FIG. 3 showing the packaging material in the unfolded state, the box body 3 is connected to the back plate 6, the side plate 7, the front plate 8, the side plate 7, and the glue margin 9 in series. 9 is affixed to the inner side of the box of one side plate 7 so that the four side plates are arranged in four directions, and the front plate 8 and the back plate 6 and the lower side portions of both side plates 7 are folded. The bottom surface plate 11 is configured by overlapping and bonding the bottom surface plate constituent pieces connected via each other.

The lid 4 is integrated with the box body 3 as shown in the developed blank (FIG. 3), and as shown in the figure, a folding portion 12 is formed on the upper side of the back plate 6. It is connected through. Therefore, after the opening operation is performed as will be described later, the lid 4 can be rotated around the upper side of the back plate 6 and the outlet 2 can be opened and closed.
Further, as shown in FIG. 1, the front body of the lid 4 is connected to the front hanging plate 13 that overlaps the front plate 8 when the lid is closed, and the left and right side plates are respectively connected to the left and right side portions when the lid is closed. 7 is connected to the front hanging plate 13 and the horizontal hanging plate 14 that are adjacent to each other, the position of the side hanging plate 14 near the lower end of the side portion on the front hanging plate 13 side. A tongue piece 15 extending from is attached to the inner surface of the front hanging plate 13.

Of the drooping plates 13 and 14 on the three sides of the lid, each of the drooping plates 14 has a first region 17 divided by a breakable separation line 16 at the rear portion (back plate side) of the drooping plate 14 as a side plate. 7 is attached. By attaching the first region 17 to the side plate 7, an unauthorized lifting operation on the lid body 4 is suppressed, and the first unauthorized opening that is separated when the container is opened by raising the lid body by attaching the first region 17. A regulating means 18 is formed. Since each of the horizontal hanging plates 14 has the first unauthorized opening restricting means 18 as described above, when the lid 4 is lifted, the first unauthorized opening restricting means 18 becomes the outer surface of the side plate 7 as shown in FIG. In addition, even if the lid 4 is returned, a parting trace appears clearly, and it can be seen that the opening operation was performed even when the lid was closed.
In order to make it possible to easily separate the first unauthorized opening restricting means 18, the separation line 16 is constituted by discontinuous cuts so that the division proceeds more reliably and smoothly as shown in FIG. 1. Therefore, a Y-shaped cut is formed in which the lower side of the horizontal hanging plate of each cut is opened, and the size of the cut portion is formed sufficiently longer than that of the perforation separation line type.

The front hanging plate 13 is also devised for the same purpose, and includes a separating line 19 composed of a pair of parallel cuts continuous to the lower side and breakable breaks connecting the upper end positions of the cuts. The 2nd area | region 20 connected via this is stuck on the front board 8. FIG. By attaching the second region 20, second tampering restricting means 21 that separates when the container is opened by raising the lid is formed on the front hanging plate 13.
The second unauthorized opening restricting means 21 also remains on the front plate 8 when the lid body 4 is lifted, and the broken trace can be clearly confirmed even when the lid body 4 is restored. Therefore, it has the effect of suppressing unauthorized opening. Of course, if a normal user lifts the lid 4 by a normal operation, the portion formed by the discontinuous cuts is easily broken, and the normal opening operation is not hindered.
As described above, since the first unauthorized opening restriction means 18 and the second unauthorized opening restriction 21 are provided on the three sides of the lid body 4, this operation is surely performed even if the lid body 4 is lifted with a slight force for the purpose of unauthorized opening. In addition, it is possible to prevent an illegal act such as mischief, by suppressing an operation to widen the space between the opposing surfaces of the face plate and the drooping plate. Of course, the gap between the facing surfaces of the face plate and the hanging plate is narrow and kept in a tightly joined state, so that foreign matters can be reliably prevented from entering during the distribution process and display.

Further, as described above, the tongue piece 15 is attached to the inner side surface of the both sides of the front hanging plate 13, and a step corresponding to the thickness of the tongue piece is formed on the upper side of the tongue piece 15 as shown in FIG. A lid opening preventing means 22 is formed as a part. As shown in FIG. 2, the lid opening preventing means 22 is engaged with and disengaged from a locking tongue piece 23 folded to the surface side of the front plate 8 at each of both ends of the upper side of the front plate 8. As shown in FIGS. 2 and 3, the shape of the upper side portion of the front plate 8 between the locking tongue pieces 23 is a concave shape that protrudes downward, and the locking tongue pieces A portion between 23 is a portion where the front plate 8 is not present. Then, the lid 4 is closed and the lid opening preventing means 23 is locked to the locking tongue piece 23 so that the closed state of the lid 4 is maintained. If the lid 4 is lifted by a normal operation from this closed state, each of the locking tongue pieces 23 bends and the lid opening preventing means 22 is removed. In this way, in the present paper container 1, even after the initial opening is performed, the outlet 2 is properly closed by the lid 4, so that foreign matters can be prevented from being mixed in this respect.

The partition 5 is made of a paper board having a width that can be accommodated in the box body 3, and the paper board is formed by cutting a pair of upright plates 24 connected to each other as shown in FIG. A stop piece 25 is provided. Then, by folding each of the pair of upright plates 24 excluding the locking pieces 25 into a chevron shape, each of the locking pieces 25 is brought into a uniform state with the outer bottom plate 26 from the upright plate 24, and A locking piece release hole 27 is formed at each base end of the upright plate 24 due to the release of the locking piece 25, and the locking piece of the other upright plate 24 is formed in the locking piece release hole 27 of one upright plate 24. 25 is locked, and the folded state of the pair of upright plates 24 is maintained. Thus, since the structure of the partition 5 itself is very simple and can be easily manufactured, even if the partition 5 is incorporated in the box body 3, the manufacturing cost of the paper container is not increased.
And since the arrangement of the stored items A is maintained by this partition 5, even if vibration is applied to the box body side at the time of initial opening or lid opening / closing, the arrangement of stored items will not collapse and can be easily taken out. Become. In the figure, the storage items A are shown as being vertically arranged, but may be stored in a stacked state for each section.
